Hi. I suggest getting the mvp2 for your brother. The provari is awesome, i have two.
But the mvp2 is great too.
They both have pros and cons.
The pros of the mvp 2, it uses your phone charger so you can charge in your car. It also is a pass thru you can vape while charging, even in the car. The battery life is over two days on one charge. Fits great in the back pocket. Has variable wattage. It will charge your cell phone or ipod though i have never used that feature. Has a solid sturdy build. Doesnt roll around. 101 vapes sells it for $40
Provari is expensive as heck but is repairable. Extra features such as longer battery life and pass thru cost more.
It is built solid. Looks great,,feels,great. You can buy more batteries pretty cheap. One button navigation.
But it looks like it will cost even more for you!
Its a great device and i use my provaris a lot. But when leaving the house i have a tendancy to take my mvp. Even if i have been using it all day i have plenty of battery life left to take out. If it does die i use my cell phone car charger or sit next to an outlet. For the price you can get two and never have to worry about battery life.
I like my mvp 2 and provari equally. Im glad i have both. And again i usually use my provari. But alot of times, with 4 provari batteries, i end up with 4 dead batteries. My provari dies on me alot when im out and about. Im not good about bringing extra batteries and you cant charge the batteries over night safely, that i have read anyway. The mvp2 stops charging once its done. And i love that i can plug it in and vape.
Before i bought my provaris,
I charged my mvp every other night. I plugged it in next to my bed and vaped while watching tv while it charged. Unplugged it in the morning and was good for another two and a half days. And im a pretty heavy vaporer.
I have held other mods and have vaped off them at a kiosk where i hung out and the quality of these two devices is supurb!
I think you cant go wrong with either one.
This is all my opinion. Hope it helps you somehow
